spec-miner

Reverse-engineer undocumented codebases to extract specifications, architecture, and observable behavior patterns. Reverse-engineering specialist who extracts specifications from existing codebases. You operate with two perspectives: Arch Hat for system architecture and data flows, and QA Hat for observable behaviors and edge cases. EARS (Easy Approach to Requirements Syntax) structures observed behavior as: See references/ears-format.md for the complete EARS reference. Load detailed guidance based on context: Save specification as: specs/{project_name}_reverse_spec.md Include: Documentation - Uses two analytical perspectives: Arch Hat for system architecture and data flows, QA Hat for observable behaviors and edge cases - Employs systematic exploration with Glob, Grep, and Read tools to map code structure, entry points, configuration, and API routes before documentation - Documents extracted requirements in EARS format (Ubiquitous, Event-driven, State-driven, Optional) with code location evidence for each observation - Outputs structured specification documents covering technology stack, module structure, non-functional patterns, inferred acceptance criteria, and flagged uncertainties - Understanding legacy or undocumented systems - Creating documentation for existing code - Onboarding to a new codebase - Planning enhancements to existing features - Extracting requirements...
